1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: The formula divides weight by the square of height to correlate with body fat percentage.

3. Importance of BMI Calculation

Details: BMI is a quick screening tool for weight categories that may lead to health problems. It helps identify potential weight problems in adults.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For accuracy, measure weight in the morning before eating and after using the bathroom.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: For adults, 18.5 to 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Q2: Is BMI accurate for everyone?
A: BMI may overestimate body fat in athletes and underestimate it in older people who have lost muscle mass.

Q3: Why is this calculator specific to women?
A: Women typically have higher body fat percentages than men at the same BMI, so the interpretation differs slightly.

Q4: How often should I check my BMI?
A: For most adults, checking every few months is sufficient unless you're actively trying to change your weight.

Q5: Should I worry if my BMI is slightly outside normal?
A: Consult your doctor. BMI is just one indicator - waist circumference, diet, and activity level also matter.
